The AirTAC GC40015ALF2 AirTAC F.R.L. Combination PT1/2 Low Pressure is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has PT1/2" ports, a 40 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40015ALF2 is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply package. This configuration is the size 400 unit with a PT1/2 port (PT thread standard), a 40 um filter element, an automatic drain on the filter bowl, a low-pressure-type regulator, and a fitted square gauge reading in psi. The automatic drain ejects collected condensate without anyone opening the bowl, which suits installations that run unattended or are awkward to reach, and the lubricator meters oil mist into the air line to keep downstream air tools and cylinders lubricated.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT, G (BSPP) or NPT threads, manual or automatic drains, a 5 um filter element (code W) in place of the standard 40 um, gauge scale choices, and an optional reverse/check valve. Bowl material is polycarbonate on sizes 200-400 and aluminium alloy on size 600. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. The combination has no separate bracket code — the three units couple together with their own mounting hardware. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination. Constituent units, orderable separately as spares: GF400-15 filter, GR400-15 regulator and GL400-15 lubricator.
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Feeds a stamping or clinching press cylinder with filtered, regulated and lubricated air. The automatic drain keeps the bowl clear across shifts without an operator stopping to bleed condensate, and the psi gauge gives the line technician a direct reading of set pressure.
Supplies the cylinders and air actuators on a cartoning or case-packing conveyor. The 40 um element removes water and particulate before they reach valves, the low-pressure regulator holds the gentle pressure small actuators need, and the lubricator mists oil to keep sealing surfaces moving smoothly.
Conditions the air feeding multiple pneumatic stations on a weaving line. Automatic drainage handles the condensate load from a long compressed-air run, the lubricator protects downstream cylinders running all day, and the included bracket lets the set mount directly at the machine frame.
Start with the port step: this unit is size 400 with a PT1/2 port, and larger sizes carry larger ports and more flow capacity, so match the size to the air demand of the machine it feeds. The drain is automatic here, which removes condensate by itself; manual-drain and differential-pressure-drain versions exist if you prefer a simpler bowl or a drain tied to pressure differential. The filter element is the standard 40 um grade; specify code W if the application needs 5 um filtration. The regulator is the low-pressure type, chosen where the working range of the line sits below what a standard regulator is aimed at - confirm the exact regulation range with us, as it is not published as a single figure. The square gauge is fitted and reads in psi; MPa and bar scales and an external round gauge are alternatives. Thread is PT as standard, with G (BSPP) and NPT available as order options, and a mounting bracket is included.
Because flow is published as curves rather than a single rating, we do not quote one rated number for this unit. Send us your application details and we will confirm sizing against the datasheet curves before you order.
Quick checklist
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC publishes flow for this series as curves, not as a single rated figure, so we do not quote one number. Tell us the air demand and working pressure of your application and we will confirm the correct size against the datasheet curves before you order.
The L in the code marks the low-pressure regulator variant, intended for lines that run at lower working pressures than the standard regulator targets; its exact regulation range is not published as a single figure, so confirm it with us for your set pressure. The A marks an automatic drain: the filter bowl ejects collected condensate on its own, so no one has to open the drain manually on a schedule.
